This is a technique of photography, using specialized equipment or software, that captures images with elongated fields of view. It is sometimes known aswide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio. While there is no formal division between "wide-angle" and "panoramic" photography, "wide angle" normally refers to a type of lens, but using this lens type does not necessarily make an image a panorama. An image made with an ultra wide angle fisheye lens covering the normal film frame of 1:1.33 is not automatically considered to be a panorama. An image showing a field of view approximating, or greater than, that of the human eye – about 160° by 75° – may be termed panoramic. This generally means it has an aspect ratio of 2:1 or larger, the image being at least twice as wide as it is high. The resulting images take the form of a wide strip. Some panoramic images have aspect ratios of 4:1 and sometimes 10:1, covering fields of view of up to 360 degrees. Both the aspect ratio and coverage of field are important factors in defining a true panoramic image.[1]

In my own words...
Panoramas are mostly consisted of high definition pictures built up in a 360 degree environment. Panoramas are are images that are more than 160 degrees so using a wide angle lens does not automatically class it as a panorama, it only shows the type of lens that was used to take the images. panoramas do not necessarily have to be horizontal, they can be vertical as well.
Gigapan
This is a collaborative project between Carnegie Mellon University and NASA Ames Intelligent Systems Division's Robotics Group with support from Google. Its goal is to facilitate the taking of large (gigapixel) composite pictures, presenting the data as a single image and providing efficient web storage, browsing and zooming of such images. he commercially available GigaPan robotic mounts turn most digital cameras into extremely high-resolution panoramic imagers. The robotic unit guides the user through setting up a panoramic scene, then automates the image acquisition process, precisely taking individual pictures across a grid. These images are downloaded to a personal computer where free software stitches, renders, and projects the images together into a single explorable super-image. These massive gigapixel-sized images can then be uploaded to the free user community site < http://gigapan.org> which allows high-resolution images to be stored, shared, annotated, commented, linked, geolocated, and embedded on any website. The server-side technology relies on an image pyramid-tiling scheme that enables user interactions to occur in a dynamically resolving image space similar to Google Earth. When interacting with the final composite image, users can for example view the entire panoramic or macropanoramic scene and then zoom into the tiniest details in full resolution.

In my own words...
Gigapan is a process used when taking/ gathering high definition images from a grid and combining them in to a single image (Panoramic image) allowing you to zoom in and out. The images are taken by a robot designed to take multiple HD pictures. VR Photography
VR photography, or virtual reality photography, is the interactive viewing of wide angle panoramic photographs, generally encompassing a 360 degree circle or a spherical view.

In my own words...
This type of photography is high resolution and another term used in this line of work would be Gigapan, definition stated above.
